Tamra Judge, Melissa Gorga and Ramona Singer have more in common than just being “Housewives” — they have the same go-to glam squad, consisting of hairstylist Julius Michael and makeup artist Priscilla “Ms. Priscilla” DiStasio.

Westchester-based Michael and Queens-based DiStasio doll up the reality personalities for appearances, photo shoots and “Watch What Happens Live with Andy Cohen” night after night.

“Everyone thinks that we work for Bravo,” Michael told Page Six at his salon, Julius Michael Scarsdale. “We don’t work for Bravo. We work for ourselves. So every time that we do work with one of the ‘Housewives,’ it’s all request. The only time that we actually work for Bravo is press days or anything pertaining to that [like] cast photos or openers.”

“When we are at ‘WWHL,’ we’re not technically the in-house glam,” DiStasio chimed in. “So we are there upon request, which speaks volumes because we’re always there.”

So how did two artists from the suburbs of New York City become the “it” glam team for everyone from Jenny McCarthy to Lisa Vanderpump’s dog Giggy?

“Tamra was coming to New York to do ‘WWHL’ and had just announced that she was divorcing Simon,” Michael said. “And her PR lady reached out to me to do her hair for it. And at the time, Tamra was known for that really bad hairstyle, so I made her a set of hair extensions and when I showed up to the hotel, we kind of just clicked right away and I was like, ‘Hey, do you care if we put extensions on you?’”

“She’s like, ‘No, go for it!’ And she went on and people were going crazy … and then Tamra called me and asked me to fly to [Orange County, California] to do her permanent hair extensions and I did. And then [she] and I just became friends — very close friends and [my career with Bravo] just took off.”

“The day I met Julius, I knew I had a lifelong friend,” Judge told us. “He has the biggest heart and is one of the best stylists I’ve ever worked with and I’ve worked with a lot. He’s the only stylist that I close my eyes and say, ‘Do whatever you want.’ I knew when I got married to Eddie, I needed to fly him [Michael] in for the most important day of my life. He did not disappoint! I’m so proud of his success.”

Meanwhile, DiStasio hit it off with Teresa Giudice and they worked together behind the scenes for Season 2 of “The Real Housewives of New Jersey.”

She had just left her job at a local MAC store and “started a Facebook page and like 48 hours later got an email and landed [her] first show on VH1, which was called ‘My Big Friggin’ Wedding.’” The now-off-air series filmed in New Jersey, and DiStasio met Giudice while she was doing press for the show.

They’ve been together ever since.

“Priscilla is not only an amazing makeup artist, she is also one of my closest and most valued confidantes. She is like the sister I never had,” Giudice told us.

“RHONJ” would later bring DiStasio to Michael during its fourth season in 2012, but their partnership didn’t start until much later.

“We were working on ‘Jersey’ and we’d do a lot of shoots together,” he explained. “We just never really had interaction, but eventually [she] and I started talking to each other and we kind of separated the fact that Melissa and Teresa were not getting along and I was doing Melissa’s hair and she was doing Teresa’s makeup, but we put that aside and then fate brought us together. Priscilla reached out to me for a job.”

“I had been doing Scheana [Marie] from ‘Vanderpump Rules’ and then the next one that came for ‘WWHL’ was Katie [Maloney] and she needed hair,” DiStasio explained. “And I was like, ‘Well, I have the perfect person for you!’ And that’s when I contacted Julius and [he] and I turned her out. So really what brought us together were our clients.”

But working around Bravo’s biggest names is anything but easy.

“It is blood, sweat and tears,” DiStasio said of their work. “We wake up at the crack of dawn, we don’t have the typical 9-to-5. We have the 4 a.m.-’til-midnight. We’re done when production is done and that can take two days at times!”

They also work on an unpredictable “WWHL” schedule, in addition to their clients who aren’t reality stars.

“The most challenging and stressful job was when Lisa Vanderpump got super delayed and had to take a shower,” Michael told us. “We came to her suite at the Plaza, [she] jumped in the shower and me and Priscilla literally had 15 minutes to do her hair. We got to the studio with her hair half wet, makeup half done. She was going on air. The studio was in a complete panic and we turned that s–t out. I literally pulled her hair back. I clipped all extensions. Priscilla beat her face. She went out with half wet hair, a full head of extensions in the front and no one ever knew!”

“Our anxiety was so high like, ‘Oh my God, where is she?’ ‘WWHL’ was calling, ‘Is she there yet? Is she there yet?’” he added. “We’re live! We can’t show up late. There’s no pre-recording. We have to get there. So we pulled that look off.”

“She loved it!” DiStasio said. “And it made so much noise! And I even added glitter to Giggy! He was s—ting glitter that day!”

Now, DiStasio and Julius are working on their next ventures. Michael is focused on his salon and would love to start a hair extension line. Meanwhile, DiStasio just launched a three-lipstick collection with Rincón Cosmetics and is looking for another project.

“For both of us, it wasn’t an easy journey and it’s still not and to be honest, we’re in such a peak of our careers but it hasn’t even started yet,” DiStasio said. “Doing ‘Housewives’ has been a great staple to be with, but there’s so much world that the world hasn’t seen from Julius Michael and Priscilla DiStasio.”
